Anyway, I believe following explanation isn’t hard to understand.

Hamming distance, Jaro-Winkler distance, and some others are all called the Edit Distance.

Hamming distance is use to compare two strings in equal length. And it looks up one position by one position. Details please see wikipedia(Chinese)

On the other hand, Jaro-Winkler distance is used to compare two strings of either equal length or different length in more complicated behaviors Details please see wikipedia(English)
